set. The “correct answer” might be to exclude a folder or files that match a particular filename pattern with some unneeded data in the current backup set. You do this on the Exclusions tab of the Advanced Settings dialog box, as shown in Figure 3-5. FIGURE 3-5 Excluding .mp3 files from a backup set
Objective 3.1: Configure and manage backups CHAPTER 3 157 CONFIGURING VSS SeTTINGS The other tab—VSS Settings—is shown in Figure 3-6. Volume Shadow Copy Service (VSS) is the background service that, among other important functions, allows Windows Server Backup to create backups of all files, even ones which are locked by applications. All backups performed by Windows Server Backup are VSS backups, so these settings are always applied when the backup you’re currently defining is performed. The two options are: ■ ■ VSS Full Backup With this setting, the files you back up are marked as backed up in the application log file. This option is appropriate when you are not using any other backup application. ■ ■ VSS Copy Backup This is the default selection. With this option, the backed-up files are not marked up as backed up, so the backup doesn’t interfere with any other backup applications. FIGURE 3-6 Choosing the type of VSS backup Destination type After you choose which items to back up and make any desired exclusions and changes to VSS settings, you need to specify a location to store the backup. ■ ■ Back Up To A Dedicated Hard Disk This option is available only for scheduled backups. If you have a spare physical hard disk, this option offers the best performance
158 CHAPTER 3 Implement business continuity and disaster recovery for storing backups. Writing to the dedicated disk doesn’t interfere with any other I/O operations. ■ ■ Back Up To A Volume This option is also available only for scheduled backups and applies to non-dedicated volumes and mapped network drives, not optical drives such as DVD drives. ■ ■ Local Drives This option is available only with the Backup Once option. It is similar to the Back Up To A Volume option, except that you can also burn the backup to an optical drive. ■ ■ Remote Shared Folder This option is available for both the scheduled backups and immediate backups. An important limitation of saving to a remote shared folder is that you can only store one backup at the remote location. Any existing backups found at the network path are overwritten by the new backup. EXAM TIP Remember that backing up to a remote shared folder overwrites the previous backup. performance settings Performance settings are configured in the Windows Server Backup console, not the Backup Schedule Wizard or the Backup Once Wizard. The performance settings allow you to make backup operations quicker, at the expense of a longer restore operation. To view performance settings, click Configure Performance Settings in the Actions pane of the console, as shown in Figure 3-7. This opens the Optimize Backup Performance dialog box, shown in Figure 3-8.
